Smoke from the King Fire returned to the Reno-Sparks area late Sunday afternoon, prompting officials to issue a warning for people in sensitive groups.

The Washoe County Health District's Air Quality Management Division reported an air quality index of 103, a level unhealthy for older adults and children, as well as people with heart or lung disease.

Officials say people in those groups should reduce outdoor activities.  They expect a similar air quality forecast for Monday.
